استجابة ثلاث ضروب من الكجرات للإدارة المثلى للتسميد

Abstract EN

This experiment was conducted to study the effect best management of fertilization on the colyx leaves content of the active substance and some nutrients (N, P, K, Mg, and Ca) for three types of Hibiscus red, white and Striped bag in Al-Husseiniya, - Al – Tali'ah District, Babylon Province.

The experiment consisted of three types of Hibiscus(red, white and striped bag) and it was fertilized with (600) kg h-1 DAP (N: P18: 46)% Side dress.

In addition to the organic fertilizer, 20 ton h-1(organofert) mixed with soil and spray by mixed of leaves fertilizers (Viva + Foliacon + Pro-sol) In a simple experiment based on CRD design.

After the completion of the Flowering phase, the percentage of Hibiscin μg g-1 dry weight, concentrations of(N, P, K, Mg and Ca)% in calyx leaves were measured.

The results of the statistical analysis of the least significant difference (LSD) for the mean of the treatments below the significant level 0.05 showed the superiority of Striped followed by red and white sequentially in the calyx leaves content of the active substance Hibiscin, N, K, Mg and Ca% sequentially and the values (24.77, 18.43 , 12.13) μg g-1 dry weight , (2.96, 1.69, 0.73)% , ( 2.5, 1.51, 0.81)%,(2.20, 0.85, 0.52)%,(3.47, 2.34, 1.83) % respectively.

White beating was excel followed by the Striped and the red for the phosphorus concentration (0.64, 0.39 and 0.27)% respectively.
